MANLOVE BUTLER, OF VERNON, INDIANA, ASSIGNOR OF ONE-HALF OF HIS RIGHT TOBENJAMIN O. BAKER, OF SAME PLACE.

HORSE HAY-RAKE.

SPECIFICATION forming part of Letters Patent No. 223,316, dated January6, 1880.

Application filed November 22, 1879.

To all whom it may concern Be it known that I, MANLOVE BUTLER, ofVernon, in the county of Jennings and State of Indiana, have invented anew and valuable Improvement in Hay-Rakes; and I do hereby declare thatthe following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a plan view of thisim'ention. Fig. 2 is a central vertical section of the same.

I 5 This invention has relation to hay-rakes; and it consists in theconstruction and novel arrangement of the annularly-grooved rakebody,the pair of clamping-levers, connected by a spring and engaging theannular groove of the rake-body, and the gravitating latch,

all as hereinafter shown and described.

In the accompanying drawings, the letter A designates the main body orroller-beam of the rake, having the double teeth B B on opposite sidesthereof, and a central annular groove, a.

0 represents an upper, and D an under, clamping-lever, whereof the endsare beveled in arc form to fit the annular groove, as shown 0 at b. Theouter edges of these lever ends are rounded and bound with a strongmetal band-connection, 0, which is firmly secured to both levers. Slots(1 are made in one end of this band-connection to permit of a certainamount of adjustment to compensate for wear 3 5 and preserve the springaction. Near their outer ends the levers are slotted for the passage ofthe gravitating latch E, which is pivoted in the slot of the lower leverand extends through the slot of the upper lever, falling into engagementby the operation of its lower weighted arm, 6. When this latch isdisengaged the spring-connection opens the clamping-levers and allowsthe rake to turn over and deposit its load. Then the clear teeth 5 arepresented for work, and the levers, being brought together, again clampthe rake-body and hold it firmly, the clamping action being secured bythe falling of the latch.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination, with the rake-body A, having the double teeth andannular groove a, of the clamping levers having the areshapedbearing-ends b, the adjustable spring band-connection c, and thegravitating latch E, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

MANLOVE BUTLER. Witnesses:
